Another object of the invention is to provide a wrench having a handle which can be readily set at different angles in relation to the jaws, whereby the same shall possess great efficiency and utility.

To this end the invention consists in the novelconstruction and arrangement of the component parts, as hereinafter fully described, and set forth in the claims.

In the accompanying drawings, Figure l is a side view of my improved tool and showin g the wrench applied to a nut, indicated by dotted lines. Fig. 2 is a front'view of the same. \Fig. 3 is a view of the opposite side of the tool and showing the same used as a pipe-wrench, the pipebeing indicated by dotted lines. Fig. 4: is a back view of the tool as applied in Fig. 3. Fig. 5 is a side view showing the handle set in position to allow the screw-driver to be used. Fig. 6 is an enlarge'd outer end view of the tool in the condition shown in Fig. 1. Fig. 7 isatransverse section on line X X in Fig. 1, viewed in the direction indicated by the arrow 1. Fig. 8 is also a transverse section on line XX, viewed in the direction indicated by arrow 2. Fig. 9 is an enlarged detail View of the supplemental jaws or g1-ipping plates and the arms by which they are carried on the main adjustable jaw; and Fig. 10 is an enlarged longitudinal section of the adj ustable jaw, showing the supplemental jaws in operative position.

Referring to the drawings, A and A denote the two jaws of the monkey-wrench. The jaw A is stationary and is formed with a guide a, in which is disposed a longitudinally-movg and h, respectively, as clearly shown in Figs.

9 and 10. When the jaws A A are to be used as a monkey-wrench,the said plates cand dare arranged so as to present the smooth face e'of theplate c to the face of the stationary jaw A, as shown in Figs. 1, 2, and 5, and when said jaws are to be applied as a pipe-wrench the plates are arranged to present the serrated or toothed face h of the plate at to the face of said stationary jaw, as shown in Figs. 3, 4:, and 6.

The combined plates and d constitute supplemental pipe-jaws which are particularly designed to be applied to pipes of verysmall diameters, as clearly shown in Fig. 10. Said gripping-plates are sustained in position on the adjustable jaw A by means of a pair of parallel arms i i, pivoted to the same by means of a pin j, which arms embrace the sides of said jaw and are integrally united by a yoke 70, which extends around a head Z, formed on the rear end of the jaw,'anda setscrew m, working in said yoke and bearing on said head, as more clearly shown in Figs. 6 and 10. Said arms it each have one of their edges formed with serrations or teeth-n n to correspond with the plate'c, thus afiording a more firm grip when the jaws are applied as a pipe-wrench.

The adjustment of the jaw A is effected by means of a right-and-left screw .13, which engages a screwthreaded aperture 0 in the aforesaidhead land a like aperture 19, formed in an extension t on the rear end of the stationary jaw A, said screw being provided with a thumb-piece g, by which to turn the same, and thus impart longitudinal movement to the shank b.

0 denotes a segmental rack which is rigidly. secured to the stationary jaw A and consists of a pair of circular notched plates disposed at opposite sides of the shank b. The forward ends of said plates converge and embrace an ear 0', projecting from the lower or back face of said jaw, and are fastened thereto by means of a rivet s. The rear ends of said plates converge similarly and embrace the extension 25 and are attached thereto by a rivet u. The extreme rear end portions of the plates are made tapering, and between said portions is a V-shaped space, (indicated at 11,) thus forming a device which can be utilized for pulling tacks, rho. At the intermediate portion of the rack G are secured a pair of guide-pieces w w, preferably by means of rivets or, between which guide pieces the aforesaid shank b slides.

lVhile I prefer to secure the rack G to the stationary jawin the manner just described, at the same time it will be observed that the same may be formed integral with said jaw, and, furthermore, the guide-pieces referred to may be formed integral with said rack.

By employing a right-and-left screw for operating the shank b it will be seen that the jaw A can be very quickly set at the required distance from the stationary jaw.

D is a bifurcated handle which embraces opposite sides of said rack O and stationary jaw A and is pivotally attached to the latter by means of a pin a. In the bifurcation of said handle is disposed a dog I), which slides in longitudinal guide-slots c 0, formed in the handle, and is'held in engagement with said rack by means of a coiled spring (1, bearing with one end against the free end of the dog, which spring surrounds a stem 6', formed on the dog, and has its opposite end suitably seated in the handle. Thus said handle can be readily swung to different angles in relation to the jaws A A when desired and locked to the rack. Said dog I) is formed with a thumb-piece f, by which to draw the same outof engagement with said rack. The jaw A is formed with a transverse notch g,which is adapted to be used for turning various objects, such as screweyes, thumb screws, hooks having screw-threaded shanks, (KEG.

The inner end of the shank b is formed with a tongue h, constituting a screw-driver, which can be conveniently used when desired.

What I claim is-- 1. In a wrench, the combination of a stationary jaw, a handle pivotally attached thereto and provided with means for locking the same at various angles to said jaw, a longitudinally-movable shank sustained on said jaw, an adjustable jaw fixed to said shank and formed wedge shape, a pair of integrallyformed interchangeable gripping-plates disposed divergent to each other and sustained on said adjustable jaw, and a screw for moving-the aforesaid shank as and for the purpose set forth.

2. In a wrench, the combination of a stationary jaw, a segmental rack rigidly secured to said jaw, a handle pivotally attached to the jaw, means on the handle to engage said rack to lock the handle at various angles to the jaw, a longitudinally-movable shank sustained on said jaw, an adjustable jaw fixed to said shank and formed wedge shape, a pair of integrally-formed interchangeable gripping-plates disposed divergent and sustained on said adjustable jaw, and a screw for moving said shank as and for the purpose set forth.
